If You Want to See a Supermoon in 2017, You’d Better Do It Tonight

On Sunday, December 3rd, the only supermoon of 2017 will shine bright in the sky. So if you’re into that kind of thing, make sure to grab a hat and scarf and take yourself out into the winter night for some A+ viewing.

A “supermoon,” for those of you not up with the lingo, is a popular term for a peridean full moon – which happens when the moon is full at the same time that it’s variable orbit happens to bring it closest to the earth.

When the moon is full at a shorter distance from earth, it can appear 14% larger and 30% brighter in the sky. You won’t need your eclipse glasses or anything, but it could still be fun to get out there with the family and maybe some hot cocoa, and add a new tradition to the holidays.
